P. BEGHETTI WIRE TWISTING DEVICE Original Filed Feb. 29, 1928 April s, 1930.

Reissued pr. 8, 193() UNITED STATES VPETER. BEGHETTI, OF SAN FRANCISCO, CALIFORNIA WIRE-TWISTIN'G DEVICE riginal No. 1,698,989, dated lJanuary 8, 1929, Serial No. 257,849, filed February 29, 1928. Application for reissue filed November 13,

This invention relates to wire tightening and twisting devices as used by the builders of wooden forms for casting concrete walls and the like, and particularly to the type of such a device disclosed in my copending application filed under Serial No. 201,787 on June 27, 1927, entitled Wire pulling and twisting tool.

The objects of the invention are to provide a device of the character mentioned which will be easier to operate and which will more effectively clamp the wires to be pulled and twisted.

In the drawings accompanying this specification Fig. 1 is a perspective View of one form of my improved wire twisting device with wire receiving jaws open.

Fig. 2 is a perspectiveview of another form of my improved wire twisting device with 20 wire receiving jaws open.

Fig. 3 is a side view of the forward end of the device of Fig. 1 with the near side wall of the upper jaw broken away, and with the jaws closed upon a wire dotted in place.

Fig. 4 is a side view ofthe forward end of the device of Fig. 2 with the jaws closed upon a wire dotted in place.

As with my previous disclosure-in the copending application referred to my device consists of a carpenters brace-like implement, but instead of a bit chuck at the forward end it is provided with means for holding a pair of wire strands so that the wires may be twisted together upon turning the brace, and the tool is provided with a forwardly projecting nose or heel so arranged that itv may be placed against the studding or side of the wall form andused as a fulcrum for pulling the wires, before and at intervals while twisting the same.

The improvements herein consist principally of the provision of a pair of jaws for gripping the wire ends and a handle for operating the jaws, by means of which any desired grip may be placed upon the wires and the handle locked in place.

In the drawings, both Figs. l and 2, the carpenters brace portion is shown at 1 provided with revolvable sleeves at 2 and 3 for 1929. Serial N0. 406,968.

grasping in the hands to operate like any common carpenters brace.

In Figs. 1 and 3 the forward end of the brace is formed into a shank 4 provided with astep or jaw 5 and a socket 6 to which a yokelike aw 7 is pivoted by means of a bolt 8.

This jaw 7 is arranged to swing down over the jaw 5 as shown in Fig. 3 and to clamp a wire, or pair of wires to be twisted. The position of the wire when clamped is indicated in the dotted lines 19 and it will be seen that the wire is kinked substantially at right angles in two places where it is gripped between jaws 5 and 7.

A handle 9 extends from the pivoted jaw 7 so that the jaw may be clamped upon or released from the wires, and the handle engages any of a series of ratchet teeth l() formed on the brace to hold the' jaws in clamped position.

The handle is preferably provided with a ilattened portion at 11 adapted to engage the ratchet teeth, and is made of spring metal Hattened at 12 so arranged as to yieldingly hold the portion l1 against the ratchet teeth.

Projecting forwardly and outwardly from the forward end 6 of the tool is the fulcrum nose 13, while projecting upwardly from end 6 is a horn 14 which functions as a separator for two strands of wire held in the tool for twisting.

In Figs. 2 and 4 all parts from 1 to 4, and 9 to 13 described for Figs. 1 and 3 are duplicated here and function the same as for Figs. 1 and 3, hence bear the same numerals.

The difference in the construction. of Figs. 2 and 4 is that the upper jaw 15 is not of yoke form, but has its ends projecting freely at opposite sides of the Lipper jaw handle, and the lower jaw 16 is similarly formed so that when the jaws are open as shown in Fig. 2 the wires to be twisted together may be freely slipped in place from opposite sides instead of being poked longitudinally into place from in front of the tool.

In Figs. 2 and 4 the wires are kept separated by the lower end 17 of the handle which is pivoted to the shank of the brace by a bolt 18.

The wire pulling fulcrum 13 shown in Fig.

2 isreversely curved from that shown in Fig. 1 but functions the same as it provides a ful-i crum for` the device forwardly of the wire clamping jaws and outwardly from the main axis X-X of the brace..

In Fig. l the closed position of the jaws is shown with wire or wires 19 dotted in place and kinked by means of a rear lip 15 on the upper jaw coming down in back of the lower jaw 16.

While I show the preferred form of my tool provided with `a carpentersfbrace portion it is evident that the peculiar'construc-- tion of the jaw varrangement of this `tool'has especial value for concrete form workers as a simple hand tool as shown in Figs. 3 and 4 with suitable lengths of handles without `the brace portion, especially when working in corners Where the brace would interfere with twisting of the wires by revolving the tool.

Having thusdescribed my improved wire `twisting device, I claim:

1. A mechanics tool comprising a carpeni ters brace frame with a shank at the forward end thereof, a Wire clamping jaw operatively mounted on` said shank, an operating handle extending from said aw, and ratchet means on said brace frame adapted to engage said `handle to hold said jaw `in clamped position,

4and clamping-means on said shank cooperating with said j aw adapted to kink said wire in clamping the same.

2. A mechanics tool comprising` a carpenters brace frame with a shank at the forward end thereof, a wire clamping jaw operatively mounted on 'said shank, an operating handle extending from said jaw, and means on said brace frame adapted to engage said handle to hold said jaw in clamped position and means on the forward end of said tool arranged and a dapted to space a pair of wires clamped by said jaw.

3. A mechanics tool comprising a carpenters brace frame with a shank at the forward end thereof, a pair of wire clamping jaws on the forward end of said shank, oneof said ,i j j jaws pivotally mounted on the shank so as to open and close with respect to the other, a

handleverextendingrearwardlyfromthe pivoted jaw` foroperatingthe same, and meansk `on the brace frame portion arranged and ,y

adaptedto hold the handle locked kat various points of adjustment with jaws in closed pov sition. j

4. A mechanics tool comprising a carpenters brace frame with a shank at the forwardk i end thereof, a pair of wire clamping jaws on the forward end of said shank, one of said jaws pivotally mounted on the shank sofas to open and close with respect to the other, means for locking' the jawstogether, and one of saidvjaws extending forwardly and outwardly beyond the other of said jaws.

5. A mechancs tool com risinor a car en- "levers" pivoted together adjacent one end, a
